stains, A oonronarron or ELECTRIC SIGNAL AND AIR-BRAKE-HOSE NIPPLE.
Application filed March 7, 1921. Serial No. 450,197.
My said invention relates to a combina tion electro-pncumatic hose nipple for air brakesand is intended primarily foruse as a means for connecting an air-brake hose to an angle cock though not necessarily limited to such use. It is an object of my invention to provide common means for connecting up an air-brake hose and completing an electric circuit through a train.
It is a further object of my invention to provide a connector of the'type referred to which shall effectively protect the electric conductors from breakage or impairment due to rain, dust, accidental blows and jars, and the like.
A further object of my invention is to provide a unitary device which shall be inexpensive and effective for its purpose and yet be capable of manufacture by ordinary methods and the parts of which may be easily and quickly connected, and disconnected;
Referring to the acconupanying drawings which are made a part hereof and on which similar reference characters indicate'si'mi lar parts,
Figure l'is an elevation of the device in working position, I
Figure 2, a view of the device partly in section,
Figure 3,'a view looking in the direction of the'arrow in Figure 2, V ,Figure 4, adetail of a part shown in section in Figure 2. v
Figures and 6 are side and end views of fiber blocks used in making the electrical connections,
Figure 7 is a detail of a polarizing pin, Figure 8 a detail of an electric connector, and
Figure 9 a sleeve in which said connector engages. w
In .the drawings 10 indicates an angle cock connected in ordinary fashion to a section ot'train pipe 11.
A hose nipple 12 is attached to the angle cock by standard pipe threads in the usual manner and this nipple has at its opposite end an annular boss 13 for attachment of a hose section 14 held in place by a clamp 15 in conventional fashion; Preferably the hose section contains wires 16 embedded in the wallsthereof although thefwires extending from one train unit to another may be supported in other wayso On the body of the hose nipple is a collar 17 merging into a hollow extension 18, form ing a socket. A pair of passages 19 lead throughthe collar and the extension and into the open central space of said extension. In said space I provide a block 20 held in place by a set screw 21. This block has three openings extending therethrough, of which openings 22 contain sleeves 23 of conducting material to which are attached wires 16 passing from the hose section through passage 19 and attached tothe collars by pins Permanent connection of the wires to the sleeves is insured by soldering the wires and pins to thesleeves; The wires are insulated from the nipple in passages 19 by any conventional means such as wrappings of rubber tape or the like. A second block 25 has openings 26 corresponding to openings 22 in block 20- In. these openings are positioned slotted pins 26 for engagement with the sleeves 23, these pins forming expa nsible electrical connectors between the wires soldered thereto and the sleeves 23.. The blocks 20 and 25 are made of insulated mater al, preferably fiber. An opening 27 in block 20 is provided to receive a polarizing pm 28 located in opening 28 .p v n a or block 25 and acting to prevent clossed connections and thereby to maintain the polarity of the system: A disk 29 rests against the end of the extension 18 and acts to hold the pins 26 and 28 in position, said.
diskbeing fixed to block 25 by a screw 30. Holes are provided in the disk at 31 for passage of wires from the conduit 32 to the pins 26. A thimble 33 on the conduit rests against disk 29 and the thiinble 33 and disk 29 are held in place by union nut 34:.
In use the parts are assembled as shown in Figures 1 and 3, the wires 16 being fixed toblock 20 and then inserted through pas sages 19 so as to bring the block into seating position against a flange 35 (Figure 2). The wires 16 are led into the openings'in the walls of hose section 14:. which is positioned on the nipple at 13 as shown in Figure 1. The conduit 32 is then positioned as shown in Figure 2 improper positioning being prevented by pin. 28. The union nut 34 being now screwed down holds allof the parts firmly in position. "-VVhen it becomes need be done is to remove the ordinary coupler and the clamp 15 and pull the hose. oh the nipple, leaving the wires 16 in place and then replace the hose by a new one in the manner above indicated.
Modifications of my device will occur to those SlIlllQCl lII the art and therefore I do not limit myself to the precise form shown in the drawings and described in the speci fication, but only as indicated in the appended claims.
Having thus fully described in said invention what I claim as no and desire to secure by Letters Patent, is:
